Code refactoring is the process of restructuring existing code without changing its behavior. The primary goal of refactoring is to improve the readability, maintainability, and extensibility of the code by making the code simpler and easier to understand. Additionally, refactoring can help to make the code more efficient in terms of performance and memory usage.
